Rethinking the incandescent lightbulb

A team of material scientists and engineers affiliated with a host of institutions in China took a new look at the incandescent light bulb and found a way to improve its efficiency. In their paper published in the journal ...

Reducing molten salt's corrosive effect

Oak Ridge National Laboratory scientists recently demonstrated a low-temperature, safe route to purifying molten chloride salts that minimizes their ability to corrode metals. This method could make the salts useful for storing ...

Catalytic synthesis of phenols with nitrous oxide

The emission of greenhouse gases threatens the global environment, and scientists around the world are increasingly committed to addressing this issue. While many research groups focus on carbon dioxide (CO2) or methane (CH4) ...

Argon found in air of ancient atmosphere

On the massive sheets of ice that stretch across Greenland and Antarctica, the temperature is so low that not even the summer sun can melt the snow deposited onto them. As the snow accumulates without melting and settles ...

A (much) earlier birth date for tectonic plates

Yale geophysicists reported that Earth's ever-shifting, underground network of tectonic plates was firmly in place more than 4 billion years ago—at least a billion years earlier than scientists generally thought.
